Background
In recent years, minimally invasive surgery, which has the advantages of small wound, quick recovery, high cure rate and the like, has been developed rapidly, and laparoscopic surgery, which is representative of minimally invasive surgery, is widely used in the field of surgical operations, involving many kinds of diseases and operations. In minimally invasive surgery, a laparoscopic surgical access first needs to be established. Instruments for establishing laparoscopic surgical access, such as laparoscopic puncture instruments, are particularly critical for this purpose.
Typically, the laparoscopic puncture instrument includes a cannula assembly and a puncture assembly. Wherein, one side of the sleeve pipe end of the sleeve pipe assembly is provided with an air valve, and the puncture assembly penetrates through the sleeve pipe assembly. After the cannula assembly and the puncture assembly integrally penetrate into the abdominal cavity, the puncture assembly is pulled out, and then the gas valve is communicated through the pneumoperitoneum machine to inject inert gas into the cannula assembly, so that the inner wall of the abdominal cavity is effectively separated from visceral tissues, and an effective operation channel for the minimally invasive instrument to enter and exit the abdominal cavity is established. In order to maintain the sealing performance of the cannula assembly and avoid the leakage of inert gas, an airtight assembly is usually arranged in the cannula assembly, but the structure of the existing airtight assembly has defects, so that the air leakage phenomenon can occur, and the operation cannot be smoothly performed. And because the airtight assembly can not be disassembled, when a large stripped tissue is clamped in the operation process, the clamping stagnation phenomenon is easy to generate, so that the large stripped tissue is difficult to take out from the airtight assembly of the cannula assembly.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the problems that the prior puncture outfit has poor air tightness and is inconvenient for taking out large stripped tissues from a pipe sleeve component, and provides an air-tight component detachable abdominal cavity puncture outfit which comprises a pipe sleeve component, a puncture component, an air-tight component and a ventilation component;
the puncture assembly comprises a puncture cap and a puncture needle arranged at the lower end of the puncture cap;
the sleeve assembly comprises a pipe body and an assembling table sleeved at one end of the pipe body, and the other end of the pipe body is provided with an inclined opening; the outer wall of the assembling table is provided with an external thread section connected with the airtight assembly;
the airtight assembly comprises a sealing cap and a sealing base arranged at the lower end of the sealing cap; the sealing cap comprises a cap body, a puncture channel arranged in the center of the cap body, and an elastic gasket and a sealing gasket which are arranged on the periphery of the puncture channel; the elastic gasket is horizontally arranged above the sealing gasket; the sealing gaskets are provided with a plurality of sealing gaskets, and the edges of the adjacent sealing gaskets are overlapped and spliced to form a fan-shaped structure; the sealing base comprises a base body, an opening which is arranged in the center of the base body and is coaxial with the puncture channel, and reinforcing ribs which are arranged on two sides of the opening; the inner walls of the cap body and the base body are respectively provided with an internal thread matched with the external thread section of the assembling table;
the vent assembly comprises a vent valve and a vent port which are communicated; the vent assembly is in communication with the airtight assembly.
Furthermore, one end of the sealing gasket is connected with the elastic gasket, and the other end of the sealing gasket is a free end and is intersected with the puncture channel in space.
Further, the vent is in communication with the sealing base sidewall.
The utility model has the advantages that: through the airtight subassembly of special structural design, improved the airtight effect of puncture ware greatly, the gas leakage phenomenon can not appear, and airtight subassembly can be followed the thimble assembly and dismantled, and the bold is peeled off the tissue and is taken out from the pipe box subassembly of being convenient for, improves operation efficiency.

Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
The detachable abdominal cavity puncture outfit with the airtight assembly as shown in fig. 1-4 comprises a cannula assembly, a puncture assembly, an airtight assembly and a ventilation assembly.
The puncture assembly comprises a puncture cap 1 and a puncture needle 2 arranged at the lower end of the puncture cap 1.
The sleeve assembly comprises a tube body 3 and an assembling table 4 sleeved at one end of the tube body 3, and the other end of the tube body 3 is provided with an inclined opening 5; the outer wall of the assembling table 4 is provided with an external thread section 6 connected with the airtight component.
The airtight assembly comprises a sealing cap and a sealing base arranged at the lower end of the sealing cap.
The sealing cap comprises a cap body 7, a puncture channel 8 arranged in the center of the cap body 7, an elastic gasket 9 arranged on the periphery of the puncture channel 8 and a sealing gasket 10; the elastic gasket 9 is horizontally arranged above the sealing gasket 10; the sealing gasket 10 has a plurality of pieces, the edges of adjacent sealing gaskets 10 are stacked and spliced to form a fan-shaped (as shown in fig. 3), one end of the sealing gasket 10 is connected with the elastic gasket 9, and the other end is a free end and is intersected with the puncture channel 8 in space.
The sealing base comprises a base body 11, an opening 12 which is arranged at the center of the base body 11 and is coaxial with the puncture channel 8, and reinforcing ribs 15 which are arranged at two sides of the opening 12; the inner walls of the cap body 7 and the base body 11 are respectively provided with an internal thread matched with the external thread section 6 of the assembling table 4; the base body 11 can be made of rubber elastic material, the length of the opening 12 is equal to or slightly larger than the diameter of the tube body 3, and the caliber of the opening 12 is smaller than 1 mm.
The vent assembly comprises a vent valve 13 and a vent port 14 which are communicated; the vent assembly is in communication with the airtight assembly, and in particular, the vent 14 is in communication with the sealed base sidewall.
